Abstract
Description
Die vorliegende Erfindung betrifft eine Brennkraftmaschine mit einem Motorgehäuse und zumindest einer darin angeordneten Zylinderlaufbuchse sowie einer zwischen Motorgehäuse und Zylinderlaufbuchse angeordneten, insbesondere ringförmigen, Dichtung.The The present invention relates to an internal combustion engine having a motor housing and at least one cylinder liner disposed therein one between motor housing and cylinder liner arranged, in particular annular, Poetry.
Brennkraftmaschinen bei denen ein Kolben in einer Zylinderlaufbuchse geführt ist, sind beim Stand der Technik bekannt. Die Zylinderlaufbuchsen sind in das Motorgehäuse bzw. Kurbelgehäuse eingesetzt. Bei Verbrennungsmotoren mit „nasser" Zylinderlaufbuchse muss der Kühlraum gegenüber dem Ölraum abgedichtet werden. Üblicherweise werden dazu elastomere gummi-elastische O-Ringe, verwendet. Speziell der erste zur Kühlflüssigkeit weisende O-Ring wird durch heiße glykolhaltige Kühlwässer stark angegriffen und härtet aus, wodurch er seine Vorspannung verliert und die Dichtung undicht wird. Um dies zu vermeiden, muss beim Stand der Technik nach einer gewissen Laufzeit der Brennkraftmaschine die Dichtung ausgewechselt werden. Dies ist mit einem erheblichen Aufwand verbunden, da zum Auswechseln die gesamte Zylinderlaufbuchse aus- und wieder eingebaut werden muss.Internal combustion engines in which a piston is guided in a cylinder liner, are known in the art. The cylinder liners are in the motor housing or crankcase used. In internal combustion engines with a "wet" cylinder liner, the cooling chamber must be sealed against the oil chamber become. Usually Elastomeric rubber-elastic O-rings are used. specially the first to the coolant Pointing O-ring is characterized by hot glycol-containing cooling waters strong attacked and hardened which causes it to lose its preload and seal the seal becomes. To avoid this, in the prior art after a certain running time of the internal combustion engine, the gasket replaced become. This is associated with a considerable effort, since the Replace the entire cylinder liner removed and reinstalled must become.
Aufgabe der vorliegenden Erfindung ist es daher, eine gattungsgemäße Brennkraftmaschine dahingehend zu verbessern, dass die Lebensdauer der zwischen Motorgehäuse und Zylinderlaufbuchse angeordneten Dichtung erhöht ist.task The present invention is therefore to a generic internal combustion engine to the effect to improve that life between the engine case and Cylinder liner arranged seal is increased.
Dies wird erfindungsgemäß dadurch erreicht, dass die Dichtung einen ersten, an eine Dichtfläche am Motorgehäuse und/oder an der Zylinderlaufbuchse anpassbaren, Werkstoff zur Abdichtung und einen zweiten, vom ersten Werkstoff verschiedenen, elastischen Werkstoff zum Verspannen der Dichtung aufweist.This is characterized according to the invention achieved that the seal a first, to a sealing surface on the motor housing and / or adaptable to the cylinder liner, material for sealing and a second, different from the first material, elastic material for clamping the seal.
Erfindungsgemäß ist somit die Trennung von zwei Grundfunktionen bei der Dichtung vorgesehen. Als erster Werkstoff kann ein bei den vorgegebenen Umgebungsbedingungen beständiges Material, das nicht zwangsläufig elastisch sein muss, gewählt werden. Der erste Werkstoff muss sich lediglich an die Dichtfläche so anpassen können, dass er abdichtet. Dies kann auch durch plastische Verformung erfolgen. Die für das Abdichten benötigte Vorspannung wird durch einen vom ersten Werkstoff verschiedenen elastischen zweiten Werkstoff gewährleistet, der an sich für eine Abdichtung ungeeignet sein kann und lediglich die benötigte Vorspannung über einen entsprechend langen Zeitraum aufrechterhalten muss.According to the invention is thus the separation of two basic functions provided in the seal. When first material can be at the given environmental conditions stable Material, not necessarily must be elastic, chosen become. The first material only has to adapt to the sealing surface can, that he seals. This can also be done by plastic deformation. The for needed the sealing Preload is different from one of the first material ensures elastic second material, which in itself for a seal may be inappropriate and only the required bias over a correspondingly long period of time must be maintained.
Günstigerweise ist hierbei vorgesehen, dass der erste und der zweite Werkstoff jeweils eigene, vorzugsweise von einander trennbare, Bauteile der Dichtung bilden. Vorzugsweise werden der erste und der zweite Werkstoff bei der Herstellung der Dichtung somit nicht zu einem Mischmaterial vermengt. Der erste Werkstoff weist günstigerweise Polytetrafluorethylen auf, da dieses Material sich zum einen gut an Dichtflächen anpassen kann, zum anderen aber auch bei dauerhaftem Kontakt mit heißen glykolhaltigen Kühlflüssigkeiten seine für die Abdichtung entscheidenden Eigenschaften nicht verliert. Bei einer Abdichtung gemäß vorliegender Erfindung ist es hierbei unerheblich, dass Teflon selbst nicht die zum Vorspannen der Dichtung benötigten elastischen Eigenschaften hat. Hierfür ist der zweite Werkstoff vorgesehen, welcher günstigerweise in Form von, vorzugsweise ringförmigen, Spannfedern aus, vorzugsweise rostfreiem, Stahl ausgeführt ist. Die Verwendung von rostfreiem Stahl ist besonders bei stark korrosiven Kühlflüssigkeiten von Vorteil.conveniently, is provided here that the first and the second material each own, preferably separable from each other, components of the seal form. Preferably, the first and the second material at the preparation of the seal thus not a mixed material mixed. The first material conveniently has polytetrafluoroethylene on, because this material adapt well to a good sealing surfaces on the other hand, even with permanent contact with hot glycolic coolants his for the seal does not lose crucial properties. at a seal according to the present Invention is irrelevant here that Teflon itself not the needed to bias the seal has elastic properties. This is the second material provided, which favorably in the form of, preferably annular, Tension springs made of, preferably stainless, steel is executed. The use of stainless steel is especially for highly corrosive coolants advantageous.
